Application October4 14, 11953,?Se`rial No. :385,988 `6 Claims. (Cl..S0-'32) This invention relateslgenerally lto advertising -devices of autilitarian nature andparticularly to an? inexpensive, disposable safetyrazor.

An IobjectV of the invention is toiprovidea very simple, yet highlypractical, safety razor constructed asamolded plastic article having arazorbladeernbed'ded in the plastic material with its cutting edgeexposed for V`use in shaving.

Another object of the invention is to provide e safety razor having amolded plastic'bod'yor holder .formed with a razor head at one end, thevremaining-.portionof the -body providing a'handle byWhich-themazorcanvbe manipulated when shaving.

Another object of Ithe invention'is t-ofpro'vide -a safety razor, 'ofthe character referred to, in which said-head is of a shapeclosely'-simulatirlg'onehalf of the I'head of a conventionalsafetyraz'or,"`the lhead havingfaconvex face-engaging "surfaceoverlying' the vblade and a "serrated or slotted guardportionfunderlyi'ng the bladeedg'e -a'n'd 'forming a guard.

Anotherobjectv of the invention is i tofprovide *afdisp'os- `ablesafetyrazorlof the Ytype ndicatedhavinga thin,`tear away strip of theplastiornateri-al'molded over'thefcutting edge'of the blade,` said strip1bei`n`g=separable lfrom the headlengthwise of therblade'edge touncoverthe Vsame and thusex'pose it foruse, the :strip thus -providin'gavsanitaryand safetyfseal forfthe cutting edgeof the blade.

-Another objectof-theinvention is toprovide a disposable safety razor ofthe type'specitied in- -which the bladepreferably consists fof one-halfof faiconventional,

double-edged razor blade, the conventional thin, steel -a coat Yorin Aacompartment of 'alsuitcasa the farticle being particularly adaptable foruseby travelingrnen, military personnel, etc.,'not wishing to carrytheusual shaving equipment. In additio'mthe razor is'of 1a ysize lendingitself to dispensing-from a vendingama'chine and, due to its extremelylow-cost,the1article may' bezprovided free of Icharge tothe guestsohotelsfandother establishments catering Yto transients, the backsurface andthe portion of Vthe razorbody beneath the -headrprovidingunobstructed surfaces upon which advertisingm'tter'inay be `applied byprinting or bymoldirg' 'the same thereon.

A further object of'tne' invention 'isit'oprovide 'la' molded articleofthe character'i'eferred to'above Whichpr'eierably has a recess orcavityinits'rearward side, said recess providing a` shallo'wreceptacle'or 'compartment for containing `a lsupply of'lathe'ringsoap or shaving"cream nfor applying'totheface prior to usingtlre'razor, theilth- InitedStates Patent 'tutes a convexskin-engaging' surface.

Referring tothe `drawingeindetail,vthefprcsent safety razor isAVillustratedin Figs. l to 3 Aas approximately-`one and one-halt' timesits-actual size, the razorthu-s lbeing of substantially vthe same sizeas an ordinary rnatch'book. The razor has a holder or body 10 whichincludes a rectangular central plate' portion El and a lowendhicker,rectangular portion 12, -these portions togetherprovidin'ga 'handle'adapted to beheld in a hand.

4LAbo'velthe plateportionILthe razorbody is provided 'Wi'tha "forwardlyprojecting 'head portion l5 'which ex- -tendsthroughoutthe width of thebody. Thehea'd l15 ehas ian upwardly Aand 'rearwardly'extending'curved'surplaneof the plate portion '11.

`15 yand lower portion 12-are side anges or wings y22.

VFormed in the rear side of thelower'portion 12 is a rectangular recessor compartment 23.

The holder Ior body 1'0 is molded from a'ther'mo-setting -plasticmaterial so ast-o minimize the costthereof. -P`rior `to injection of theplasticito the cavity 'of 'the mold, 'the LArazor blade 20`is placed inthe cavity and against a `pernianent magnet therein which retains theblade :in

place. 'Whenth'e pla'stic 'material is injected intoi'tlie cavity of'the mold,it flows aroundthevbladel't-o provide 'the headIS in whi-ch'all but a small'lowerfportion of =the cutting edge (19 of the blade isembedded. The cavity=is -sofformed'as to cause the plastic materialfto-extendfacross the cutting edge -191in a very thin'bead or strip Z5which encloses the cutting/edgefor vlsanitary and safety reasons. Therazor blade v 20is preferablyyalthough notnecessarily, made from-aconventional double- -edged razor blade, ithe latter being broken alongYits 'median line to v'divide it'into a pair of single-edged blades.

To apply'tlie razor to use, the user holds it in one -hand and' thengraspsanendof tle strip 25'be'tween theA thumb 1arid index'nger of "theother hand. The 'strip'is'then pulled laterally across the -razortofpeel o'rtearthe strip from across theicuttingedge 19`of theblde,"soastoexposethe' "cutting edge, itlbe-ing noted .by rfencetoFig.

3 4 that this edge projects slightly beyond the forward side of the head15. The razor is then in condition for use.

After l-athering the face, the user holds the razor in upright position,grasping the anges Z2 between the ythumb and foretinger. The razor thenmay be drawn across the skin to shave the whiskers therefrom in themanner of an ordinary safety razor. During such shaving, the lather andwhiskers will enter the shallow -receptacle 26, defined by the centralportion 11, lower portion 12, wing-s 22 and the guard 18, to becollected therein. Excess lather may be ilushed from the receptacle atlany time by simply subjecting the razor to the force of 1a stream oftap water.

After completing the shaving operation, the user deposits the entirerazor in a waste basket or other receptacle to dispose of the razorwhich, as previously indicate-d, is a very inexpensive item adapted for.a single use.

lt is Within the concept 'of the invention to provide a dispensablematerial within the receptacle or compartment 23. This materialpreferably is of a whisker-lather ing nature, such as dry particles ofshaving soap. A small Wad 3i) of cellular material may be impregnatedwith the soap particles, the wad being cemented or otherwise retained-in the compartment 23. Prior to the actual shaving operation, the wadis -moistened to create a lather which then may "be 'applied to the skinof the face of `a man, or to the legs of a woman who may wish to shavehairs from the legs.

lIn lieu of the soap-impregnated wad 30, a llexible envelope 33,containing lathering cream 34, may be secured within the compartment 23.When it is desired to :apply the cream 34, the envelope 33 may be easilypunctured and squeezed or compressed to lforce the cream `from theenvelope.

Referring now to Fig. 7, -it is also within `the present concept toprovide a disposable razor in which the body thereof is molded from laflexible, heat-sealable plastic material, such as polyethylene. In thisembodiment, the body -is molded with an integral envelope portion 32having thin walls and an open end arranged either at a side or at thelower end thereof. The envelope portion 32 provides a receptacle intowhich brushless or lather cream may be placed. The edges of the open endthen may be sealed together, as indicated `at 31, by the application ofheat and pressure to seal the envelope. To prepare the whiskers forshaving, the envelope 30 is punctured to release the Whisker-softeningmedium which is then applied to the face prior to the shaving operation.

It will be observed from the foregoing that the present inventionprovides a simple, yet highly efficient and practical safety razor of adisposable type adapted for a l.single use. The razor is molded with anintegral head in which the blade is partly embedded, thus avoiding thenecessity Ifor inserting and clamping a blade at the time of shaving.The razor is 'of light weight, yet strong construction and may be massproduced at a very low cost. The razor, which is of substantially thesame Isize and shape of a match book, provides an excellent advertisingmedium, the body of the razor having Hat surfaces to which may berapplied ladvertising decals or printing, or which may be embossed withadvertising indicia during the molding of the razor.
